  3. Abstract:
  4. CO 2 removal from synthesis gas to reduce emission in the atmosphere was studied using physical absorption with the Selexol solvent. Variances of 2-5 separator units and various pressure drop patterns were utilized. Simulation results showed that the case with 4 separators and uniform pressure drop distribution leads to the optimum design, in terms of capital and operational expenditures. Since the cost model for compressors, heat exchangers and coolers is a direct function of energy consumed, the capital expenditure was optimized simultaneously with operational expenditure, and the CAPEX/OPEX analysis reflects this matter as well. This is an abstract of a paper presented at the 19th International Congress of Chemical and Process Engineering and 7th European Congress of Chemical Engineering (Prague, Czech Republic 8/28/2010-9/1/2010)
